Problem
Enterprises that offer AI‑driven or usage‑based services often rely on static, monolithic billing systems that require extensive engineering effort to modify pricing rules, support hybrid models, or track per‑token costs across multiple LLM providers. This rigidity leads to delayed price updates, inaccurate margin reporting, and operational overhead for billing teams.
Solution
Lark delivers a cloud‑native billing platform built for modern pricing structures such as pay‑as‑you‑go, hybrid, and dimensional models. Its low‑code pricing engine lets product managers define, test, and deploy complex rate plans through a visual UI or API without writing code, while one‑click price changes propagate instantly to live customers. The platform scales to handle up to 1 million billing events per second, enabling real‑time invoicing for high‑throughput AI workloads. Integrated cost‑and‑margin analytics aggregate token usage across vendors (e.g., OpenAI, Anthropic) and surface alerts for unexpected spend spikes. A white‑label, no‑code customer portal provides self‑service subscription management, invoice history, and automated top‑up or tier‑upgrade workflows, reducing the need for a dedicated billing operations team.
Target Audience
The primary customers are SaaS and AI platform providers that monetize APIs, token‑based AI services, or hybrid subscription models, as well as enterprise product teams needing rapid price experimentation without a dedicated billing engineering squad.
